and elevation, with its. longer "dimension horizontal and disposed fromfront to rear. The sides, rear and front of the plunger chamber areclosed, its topis open save for aremovable front closure later to be dcscribed, and its bottom is closed save for an opening at the front whichopening cornmunicates with ahopper 16.

'Themagazine 12 is located a little for ward. of the middle of theplunger chamber and its open" bottom communicates therewith. Asaconvenient means of construction I prefrto support the front of theplunger chamber from the magazine by flanges 17 screwed thereto, thoughthis is merely a structural detail and may bevaried without departingfrom my invention. The magazine 12 is shown as square in horizontalsection to conform to the preferred shape of'package to be vended,thoughit will be obvious that this shape may be varied to suit the selectedshape of food package to be employed. A closure 18 isypreferablyprovided for the top of the magazine and the magazine has a glass front19 to render its contents visibleto the customer.

W'ithin the plunger chamber lt'there is p'rovided'a plunger 20 of thesame shape as the chamber and adapted to be reciprocated therein, Theplunger 20 carries at one side a pin'21 which projects througha slot 22formed in the chamber wall and a link 23 connects the pin 21-with alever24; pinned to a short shaft 25 journaled in a bracket 26 whichdepends-from the bottom of the plunger chamber. Also pinned to the shaft25 there is an operating lever 27. A. tension spring 28 connected to theplunger and-to the rear wall of the plunger chamber tends to return theplunger tothe rear end of the plunger chamber 14.

.-The front face of the plunger 20 carries a series of thin knife blades29 sharpened on theirfront edges and adapted to straddle a similarseries of blades 30 carrie'dby the inner side-of the front of theplunger chamber." There is also a set of knife blades 31 on the severalviews, the reference 10 designates a base adapted to rest on a table,coun-' across the bottom of the hopper 16-,whichin the present instanceare shown as formed of right angled continuations of the vertical blades30 though these blades 31 may be separately formed if desired, theshape- Operation.

The magazine 12 is filled with the food packages to be dispensed,thelower of these resting on the bottom of the plunger cham ber and theremalmng belngvisiblethrough the glass front 19 of the magazine. If,now, the operating lever 27 be depressed it will rock the lever '24-which will, through the Hui r23, pull the plunger .20 to the frontandpusli the lowest'of the .food packages into thefront end of theplunger chamber, the remainder of the food packages being retained intheir. original position by the closed top 32.01? the plunger 20. Thefood package, the container of which is, as we viously described, ofvery frlablecharacter, will be crushed between the plunger and the frontend of the plunger chamber, the knives29, 3O materiallyaiding in thisaction. The knives 31 a 'cross the open portion 15 of the bottom of theplunger chamber will prevent any large portions of the container fromescaping through the hopper 16 and serve to subdivide any such largeparticles, as the package and its container areforcedbetween them by theaction of the plunger. Duringthis pulverizing action of the plunger exitof the material acted upon upward is prevented by a closure 33, whichcloses that portion of the top of the plungerchamber which is in frontof the magazine, and thus the package container and its contents areforced out through the bottom, the only opening through which they mayescape. The closure 33 is preferably removable for convenience incleaning the machine, j 1

, When the lever 27 is released the spring 28 will retract theplunger 20to the position indic'atedin Fig. when the lowest of the packages in themagazine will drop to a position in front of the plunger readyto beoperated upon when the lever 27 is again depressed. ug thus described myinvention, what I claim and desire-to secureby Letters Patent is a 1, Ina dispensing device, a horizontal plunger -Cl1ELIIIbGI',"2L verticalmagazine in commui'iication with said plunger chamber and located abovethe same intermediate the ends thereof, .said plunger chamber beingclosed on the side and front walls and havingan opening in the bottom"thereof adjacentsaidifront Wall and out of line with saidmagazine, aplunger in said chamber, and means-for reciprocatingsaid plunger from aposition to the rear of said magazine to a position closely adjacent thefront wall of Said plunger chamber. v
